Answer:
See below.
Step-by-step explanation:
Let x = amount of money you have in your account.
The money in your account plus the $125 extra that you need equals the total cost of the computer. 
The equation is:
x + 125 = 2250
Now we solve the equation by subtracting 125 from both sides.
x = 2125
Answer: You have now $2125 in your account

Answer:
   see below
Step-by-step explanation:
The exponent rules that apply are ...
   (a^b)(a^c) = a^(b+c)
   a^-b = (1/a)^b
   (a^b)^c = a^(b·c)
_____
These let you rewrite the given function as ...
   f(x) = (3^(2x))(3^1) = 3(3^(2x)) = 3(3^2)^x = 3·9^x
and
   f(x) = 3^(2x+1) = (3^-1)^(-(2x+1)) = (1/3)^-(2x+1)
 
        
             
        
        
        
Needing to find the circumference of a circle you you find that you need to use the equation C=2 π R 
C= 28.26 
this is how much fence they would need around the garden approximately.
